Abstract

Large-scale touch or proximity sensors, e.g., sensors that span the wall of a home or office, have recently been described in research publications. Such wall-scale touch sensing technologies enhance a wall (or room) with sensing, interactivity, and computation, while retaining the look-and-feel of an ordinary wall. Wall-scale touch/proximity sensors that have been proposed thus far are not made of modular components. As such, each wall that is to be enhanced with touch/proximity sensing abilities is custom-treated based on the size of the intended display, using a labor-intensive process. This disclosure presents a design for a large-scale touch sensor that is segmented, e.g., built using pre-manufactured and easily installable panels.
